Maybe check, whether this is really the case. Secondly, how does the linker get the information to link libgfortran? Through a linklib directive? If not, you may have to use the fpc options "-k -lgfortran" to pass the information to the linker. Passing -vt or even -va will give you further (in case of -va a huge amount) of information building your program. I do not expect any difference between 2.4.0 and 2.6.*. I am using 2.6.4 on 10.9 in combination with gfortran and it works well. Michael. P.S. can you somehow achieve, to send a plain text email. The way you did it results in a very hard to read output.
